SPRING BED-BOTTOM.

Specicaton of Letters Patent No. 19,410, dated February 23, 18-58.

To all whom it may concer/n.

Be it known that I, JACOB CoovER, of Chambersburg, county of Franklin,and State of Pennsylvania, have invented a new and Improved Mode ofConstructing Elastic Spring-Bottoms for Beds, &c.; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings and to the letters ofreference marked thereon.

The nature of my invention consists in the manner of fastening thesprings to the slats, the way of tightening the spring, and the slats asconstructed all as hereinafter shown.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

In the construction of my invention I use any of the materials commonfor such purposes.

Figure 1, is a plan view. Fig. 2, is a plan view with the top slatsremoved. Fig. 8, a bottom plan view. Fig. 4, a view of the bottom foldedtogether. Fig. 5 is a section showing one slat with joints in it.

In Fig. 1, A the frames; B, the hinges for folding the same; C, thestays to which the top slats are attached; D, the top slats; E, crossstays for steadying the same; M cross bars.

In Fig. 2, F the springs to which are at. tached upper and under slatson frames A, Gr plates attached to one end of slats and resting on crossbars M, and which are raised or lowered by screws H for tighteningsprings J the holes for inserting or removing the ends of springs F, tosuch parts of the bed as desired; K hooks or clamps for holding springsdown M cross bars.

In Figf, A the frame; D, the slats; L, the hinges for slats D to workon; M cross bars attached to frames A; Gr plates for forming a joint inslats D', for the purpose of raising or lowering them as described inFig. 2.

In Fig. 4, A, the frames; B, the hinges; D, the top slats; F, thesprings; H the screws for raising or lowering slats D; N the bands forsecuring the corners and sides of frames A; O wires attached to framesA, and cross bars M.

In Fig. 5, D, the slats raised by means of screws H; G, the joint plate;L, the hinges.

In the operation of my invention the top slats D are constructed of aseries of small slats connected with stays which form the easiest andmost elastic bottoms for beds, or mattresses. The springs are fastenedto the top slats in the same manner that they are fastened to the lowerones. slats D, on which the springs rest have a joint by means of platesGr, and hinges L, a thumb screw H passing through the plates and restingon cross bar M, is for the purpose of lowering and raising the slat, ifthe bed should sink in the center, by turning the screw it can be raisedto a proper height and thus stiffen the springs. The slats D and D onone side are provided at every inch or two with a small hook or clampeither of which will do, and opposite each hook or clamp on the otheredge of the slat a small hole. The ends of the springs are so formedthat when the last coil of the springs opposite the ends is placed underthe hook or clamp the end will force into the hole opposite the hook orclamp which will hold the springs to their place until the end of thespring is removed from the hole again. By being fastened in this way thesprings may be removed from one part of the bed to another as requiredor should the springs be too strong some of them may be readily takenout or if too weak more can be put in or those in the bed changed so asto bring the strongest springs where the most strain is on them. Heavypersons require more spring under the body that light ones so as to keepthe head and feet on a level with the body. This has been the greatdifficulty in other spring beds now in use whereas in this bed anyperson can arrange the springs or have them arranged to suit themselves.

I am aware that spiral springs and folding beds are not new, but I donot know of any other bed or bed bottom in which the springs are soeasily fastened and so readily moved to any part of the bed desired,this bottom may be upholstered and thus form of itself a complete bed orit may be used as a bed bottom.

The lower Having thus fully cleseriloeol` the construction and operationof my invention, what I claim as new and desire to secure by LettersPatent is- Constrnoting the lower slats D with joint at or near theCenter by means of plate Gr, and hinges L, and the screw H, passingthrough plates G, for raising and lowering the slats as set forth.
